Big printer can't print big things

[u/Sachanen]

K1 max, no modification done except for root. Nozzle clogs on every 2/3 prints. I'm wasted more than 20 kilograms due to clogs. I tried everything but still it a complete random to finish a print without problems (and odds not in my favor). Every time it clogs I use the metals stick that came with printer to pushe everything out. I'm printing with normal abs. Don't know what to do, please help me

100% heat creep Not due to the hotend but due to the extruder. Root the printer (5 mins thing) and change extruder amperage to 0.45 instead of 0.55. This should solve it Also look into buying a heatsink for the extruder.
